Hello municipality I’ve been working on a R8 V8 year 2007 before about 2 weeks during the ride the orange gear lamp and I could only switch manually from to audio to the tester result of the driver is defective ok I had to have the driver changed because the driver had to be set yet which was not possible it always came the message The basic setting of the gears for R-Tronic gears cannot be carried out. Technical background Shifting fork wear. The no longer possible adaptation is due to an extended way of the gearing fork. the third and fourth gearing should be affected since someone has had experience with it before?? what is advisable??? used gearbox repair?? and if you have a good starting point?? with which costs is so connected?? or is it due to something else?? much easy you have an idea I thank you already in advance quite heartily for your tips and help
